/**
 * OpenCode Provider Service — piggyback on session.prompt for structured output.
 *
 * Pattern sourced from tickernelz/opencode-mem.
 * Instead of requiring separate API keys for auto-capture, uses the connected
 * OpenCode provider (the same one the user uses for chat). OpenCode owns auth,
 * token refresh, and provider routing — no extra API configuration needed.
 *
 * Key design:
 * - Uses `client.session.prompt()` for LLM calls (no separate API keys)
 * - Simplified schema validation (not Zod — keeps bundle size small)
 * - 0-risk: every method catches errors and returns null
 * - Graceful degradation when client is unavailable
